Secunia Advisory: SA10433
Release Date: 2003-12-15


Critical:
Moderately critical
Impact: DoS

Where: From remote



Software: Cisco Firewall Services Module (FWSM) 1.x




Description:
Cisco has reported two vulnerabilities in the Cisco Firewall Services Module (FWSM) for Catalyst 6500 series and 7600 series, which can be exploited by malicious people to cause a DoS (Denial of Service).

The vulnerabilities are caused due to an unspecified error when processing SNMPv3 messages, and a boundary error when processing HTTP traffic requests for authentication using TACACS+ or RADIUS.

Successful exploitation of the vulnerabilities crashes and reloads a vulnerable device.

The vulnerabilities affect version 1.1.2 and prior.


Solution:
Update to version 1.1.3 or later.
